CONTROL MECHANISM FOR MOTOR-VEHICLES.

1 ,104, this Specification of letters Patent.

Patented July 21, 1914.

' Application filed January 19, 1912. Serial- No. 672,173.

To all whom it may concern Be it known that l, Gnosen M. Bacon, acitizen of the United States of America, residing at Detroit, in thecounty of Wayne and State of Michigan, have invented certain new anduseful Improvements in Control' Mechanism for Motor-Vehicles, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

' The invention relates to control mechanism for motor vehicles moreparticularly designed i or use in controlling the brakes and the circuitopening switch of electric vehicles, and the invention consists in: thepeculiar construction, arrangement and combination or parts ashereinafter set forth.

In the drawings,Figure l is a perspective view of the mechanismembodying my invention; Fig. 2 is a cross section thereof; and Fig. 3 isa perspective view of the late.

A and B are two adjacent pedal eversior respectively controlling themain and the emergency brakes. These levers are fulcrumed upon a bracketbearing (3 depending from the frame l) of the vehicle, which as shown,comprises two adjacent angle bars D, D with support brackets C, Csecured thereto. The levers are arranged upon the outside of thebrackets C and C and are journaled or fulcrumed upon a pin or shai'tEpassing through the brackets. This shaft also forms the fulcrum for anintermediate lever l between the brackets and which passes upwardbetween the angle bars D, D-

G- and G are the foot rests or pedals proper for the levers A. and Brespectively and which are referably provided on their inner sides withflanges G.

H is a bearing formed on-the edge of the intermediate lever F andarranged between the flanges G of the pedals G and G.

I is a notched segment secured to the lever l8 between the bars D and D,and J is a hooked dog for engaging with said notched segment to hold thesame in diiierent positions of adjustment.

The levers A and B are connected by rods K with their respective brakemechanisms (not shown), and a' lever F is arranged to cause thesimultaneous movement of both of the levers A and 3 while permittingeach. to be independently operated. Thus as shown, L is an extension ofthe lever l below the fulcrum and which is provided with laterallyextending pins L and L engaging notched bearings in downward extensionsM and M of the levers A and B. The arrangement is such that in themovement of the lever F the levers A and B are coupled thereto by thelateral extensions L and L but when said lever F remains in its normalposition either of the levers A and B may be operated independently ofeach other, and of the lever F. The dog J which engages with the notchedsegment I will prevent the return of the lever F and the levers A and Bwhen actuated thereby. To release this lock a knob or button N which maybe pressed by the foot is connected through the medium of a bell-cranklever O and rod P with an actuating rock arm J for the dog J. Thus bypressing the button N the dog J is disengaged from the segment I and allof the levers are simultaneously released.

Q is a circuit opening switch, the movable blade Q of which is connectedwith the lever 1*. ln the normal position of this lever the switch Q isclosed, but when the lever is actuated to cause the simultaneousoperation of the pedal levers A and B the switch will be opened, whichwill cut-out the power from the vehicle.

The levers A, B and F preferably project upward through the foot-boardof the vehicle body into convenient position "for operation. Thisnecessitates slots in said foot-board to permit the necessary movementof the levers and to avoid draft openings which would be formed by theseslots.

l preferably provide covering slides there- -for.

As shown, R is a plate mounted on the foot-board of the vehicle andprovided with race of the plate and permit of carpet or other floorcovering on the footever, it is desired to instantaneously operate boththe brakes. to obtain a sudden stoppage of the vehicle, by placing thefoot over the central lever F, this as well as the levers A and B willbe operated and the locking dog J engaging with the notched segment Jwill hold the leversfrom return movement. Simultaneously with themovement of the levers the movable plate Q of the switch Q will beadjusted to open said switch and cut-ofi' power from the motor, Theparts will remain locked in this position until the operator b pressingon the button N releases the 0g J and permits the springs U to returnthe levers to normal position.

What I claim as my invention is:

. 1. In a control mechanism for electric vehicles, the combination witha plurality of independently operable brake pedal levers, of anintermediate lever arranged for simultaneous operation with both of saidpedal a single foot, and a levers when actuated by d b d actuate y salneously with said pedal levers, locking.

means for said levers automatically operated by saidi-n'termediatelever, and a circuit o ening electric switch also actuated by saidintermediate lever. ,v i

3. In a control mechanism forelectric ve- A hicles, the combination witha. pair of indeendently operable pedal levers, and means orautomaticallyretracting the same, of an intermediate lever operable simultaneouslywith said pedal levers when both are en-.

gaged by a single foot, lockin mechanism for preventing the return 0trio switch connected to be opened by said intermediate lever whenactuated, and resaid levers operated by the intermediate lever, anelecleasing means for said locking means per- I mitt'mg the return ofsaid levers.

In testimony whereof I aflix my signature in presence of two witnesses.Y
